Energy Performance Certificates (EPCs) are expected to play a more strategic role in the energy transition of Greece’s building stock. A report produced within the framework of the EPBD.wise project identifies significant opportunities to improve the national system and align it with the requirements of the revised Energy Performance of Buildings Directive (EPBD). The analysis concludes that priorities should focus on strengthening the quality and reliability of certificates, improving public understanding of their purpose, and updating the technical tools that underpin them.

Among the key recommendations is the revision of the calculation methodology to be based on numerical indicators of primary energy consumption, alongside the rescaling of the energy rating system in line with the new European framework. The report also proposes modernising the design of EPCs to incorporate emerging tools such as the Smart Readiness Indicator and renovation passports, providing a more comprehensive view of buildings’ improvement potential. At the same time, it calls for enhanced mandatory training for EPC assessors, updates to the TEE KENAK software to improve interoperability with the national database, and the introduction of regular independent audits to ensure greater consistency and reliability of information. Finally, the document highlights the need for targeted communication campaigns and the establishment of one-stop shops to help property owners and occupants better understand the practical value of EPCs and gain easier access to renovation support and financing opportunities.
